Title: Improvements in or relating to sole rounding machines
IPC: A43D87/00
Filed: 1962-04-16
Abstract: 1,000,657. Sole rounding machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. April 16, 1962 [April 18, 1961], No. 14564/62. Addition to 795,764. Heading A3B. A sole rounding machine is similar to the machine in the parent specification, but has means for biasing the elements 20, 22 of the shoe positioning gauge 18 with respect to each other against the shoe and for locking the said elements against movement with respect to each other during a portion of the rounding operation. The distance between the cutter head 10 and the jack, which supports the shoe bottom-up, and thus the width of the sole margin, is controlled by a crease guide 16 during the rounding of the shank portions of the shoe and by the gauge 18, which engages the shoe below the guide 16, during the rounding of the rest of the shoe. The gauge has wings 20, 22 (Fig. 4) pivoted on a stud 24 (Fig. 1) fixed to a slide plate 28 which is biased backwards, away from the cutting knife 12 by an adjustable spring 46. Two cam followers 32, 34 (Fig. 1) are adjustably connected by screws 60, 62 respectively to the slide plate 28 and they engage heel cams 40 and a replaceable toe cam 42 respectively. Links 72, 74 connect the ends of the wings 20, 22 to a cross bar 76 centrally pivoted on a support 80 slidable in the machine frame 30, so that the wings can turn together about the stud 24 as well as relatively to each other. The support 80 is connected via a compression spring 90 and slide 92 to a cam follower 96 and cam 98. When the slide 92 moves forward it causes a lever 106 to turn about its pivot 108 and to cause a pin 100 to lock the support 80 so that the wings cannot move relative to each other. This locking occurs after the leading edge of the wing 20 (Fig. 5) has ridden on to the cap of the shoe and yielded rearwardly. The gauge thus rides smoothly on to the cap, so preventing any step occurring in the contour of the rounding cut. While the toe portion is being rounded the support 80 is unlocked by one of the pins 126 (Fig. 4) on the cam 98 releasing a lever 122 so that it knocks the pin 100 out of the locking position, but the support is locked again while the gauge leaves the cap. The crease guide 16 (Fig. 2) has rearwardly extending legs which abut against a combined lug 136 and blade slide 138, the forward and backward movement of which is limited by adjustable stop screws 144 and 148. The lug 136 is connected, via a relatively weak spring 146, a cam lever 160 and a stronger spring 156, to a cam follower 168 and a cam 166. When the cam follower moves forwards the guide moves forwards and is then prevented from moving backwards during the rounding of either shank portion, by the rotation of the cam lever 160 causing a brake shoe 164 to press down on the slide 138. A slide 170 also abuts the legs of the guide 16 and is connected to cams 174 and 176 by adjustable screws 194, 196 respectively, the cam 174 advancing the guide further, if necessary, during the rounding of the inner shank and similarly the other cam for the outer shank.

Abstract: 1,085,941. Unloading vehicles. H. J. GRIFFITHS. July 8, 1964 [April 11, 1963], No.14565/63. Heading B8E. Apparatus for loading material into a spreader comprises a container having a shaft 6, Fig. 2, journalled between side walls 2 and pivoted to one end of a frame 10 pivoted at 10a to the chassis 10b of a lorry. The container consists of walls 2, 3, a base 4 and a deflector plate 7 which is spaced from the forward edge of the base 4 and which is secured to the side walls 2. A plate 9, secured to the frame 10, is adapted to be positioned between the plate 7 and the floor 4 to constitute the fourth wall of the container. To discharge the container, the frame 10 is raised to the broken-line position by means of a ram 15, thereby causing a cable 13, connected between the base of the container and the lorry chassis and passing over a pulley 12 on an arm 11 mounted on the shaft 6, to tilt the container away from the plate 9 to provide a discharge opening. When transporting the apparatus on a lorry, the frame 10 is lowered to the full-line position, the cable 13 and arm 11 are removed and a tractor may be loaded on to the frame 10 by means of a pair of detachable ramps (not shown).

Fluid may pass between chambers 19 and 20 past the seal 18. Compressible fluid (e.g. air) may be pumped into the chamber 34 via an inlet 40, and liquid may be supplied to chamber 19 via an inlet 1A. The flow of liquid through some of the passages 25 may be controlled by a one-way valve 28, and through some of the passages 29 by a one-way valve 30. On the cylinder 1 there may be a rotary fluid connector comprising a sleeve 42 keyed to the cylinder having three inlets 43 each connected to an axial passage having an opening 43A leading to one of three circumferential passages 44A, 44B, 44C in another sleeve 44 rotatable about sleeve 42, each passage 44A, 44B, 44C having an outlet 46, these supplying fluidto inlet 40, and to wheelbrakes. The tube 4 is prevented by arms 48 from rotating relative to the sleeve 44 which is locked rotatively relative to the cylinder 1 by a spring key 50 engaging a selected one of a series of notches (12A . . . 12D), Fig. 3 (not shown), in a ring 12 keyed to the cylinder. An aircraft (e.g. a helicopter) on which the undercarriage is fitted if lashed down, may have its shock absorber partially closed while the lashings are applied or removed, the shock absorbers being opened between while to tension the lashings.
